چکیده مقاله :
زمینه و هدف : پژوهشی که پیش رو دارید، بررسی اثر ضدباکتریایی نانوذرات نقره بر روی باکتریهای گرم منفی و گرم مثبت میباشد که در جهت استفاده از آنها در تولید نانوکامپوزیت نقره با خاصیت آنتیباکتریال مناسب و زیستتخریبپذیر به روش محلول اجرا درآمده است. روش بررسی: به منظور بررسی خواص ضدمیکروبی نانوذرات نقره،در تابستان 1397(تاریخ شروع آزمایش)ابتدا نانوذره نقره به روش احیای شیمیایی با NaBH4سنتز گردید و پس از انجام آزمونهای نانومتریک UV-VIS, DLS, XRD و TEM وFTIR ، از باکتری استافیلوکوکس اورئوس به عنوان شاخص گرم مثبت، باکتری اشرشیا کلی به عنوان شاخص گرم منفی استفاده شد و بعد میزان MIC ، MBC و Inhibition Zone محاسبه شد.در مرحله بعد نانوکامپوزیت به روش Solution Blending تولید و آماده گردید و خاصیت آنتیباکتریال آن با روش Inhibition Zone بررسی گردید. یافته ها: نتایج به دست آمده حاکی از آن است که نانوذرات نقره در غلظتهای 50،20 میکروگرم بر میلی لیتر به ترتیب بر روی استافیلوکوکوس آرئوس، اشرشیا کلی اثر بازدارندگی(MIC) دارد و همچنین در غلظتهای 60 ،40 میکروگرم بر میلیلیتر به ترتیب بر میکروارگانیسمهای یادشده اثر کشندگی (MBC) دارد که بیشترین اثر ضدباکتریایی بر اساس نتایج، بر باکتری گرم مثبت استافیلوکوکوس آرئوس مشاهده شد و علی رغم این در تست هاله عدم رشد(Inhibition zone)، هاله به قطر mm 3-5 در اطراف دیسک نانوذره نقره در کشتهای میکروارگانیسمهای ذکر شده،مشاهده گردید و در تست هاله عدم رشد نانوکامپوزیت تولید شده نیز هاله ایجاد شده بر اساس مقادیر مورد انتظار بود. نتایج آزمایش ها با 3 تکرار و مقدار PValue محاسبه شده با روش ANOVA با ارزش 0001/0 P < معنادار بوده است. بحث و نتیجه گیری: نشان داد نانوذرات نقره میتواند به خوبی بر روی باکتریهای گرم مثبت و گرم منفی اثر مهارکنندگی و کشندگی داشته باشد و همچنین نانوکامپوزیت تولید شده به روش یادشده،خاصیت آنتیباکتریال بالایی دارد.
Background and Objective: This study aimed to investigate the antibacterial effect of silver nanoparticles on Gram-negative and Gram-positive bacteria and producing silver nanocomposites with suitable and biodegradable antibacterial properties by Solution Blending method. Method: To investigate the antimicrobial properties of silver nanoparticles, silver nanoparticles were first synthesized by NaBH4 reduciton and after performing UV-VIS, DLS, XRD and TEM and FT-IR tests, Staphylococcus aureus as a Gram-positive, Escherichia coli as a Gram-negative bacteri was used, investigated by MIC, MBC and Inhibition Zone. In the next step, the nanocomposite was prepared and prepared by Solution Blending method and its antibacterial activity was evaluated by Inhibition Zone method. Findings: The results showed that silver nanoparticles had inhibitory effect on Staphylococcus aureus, Escherichia coli and Candida albicans at concentrations of 50, 20 and 355 μg / ml respectively and also at concentrations of MIC. 60, 40 and 370, respectively, have the lethal effect on the aforementioned microorganisms (MFC, MBC). A diameter of 3-5 mm was observed around the silver nanoparticles in the cultures of the mentioned microorganisms and in the test of nanocomposite Inhibiion zone, the halo was created based on expected values.the results of the experiments were calculated with 3 replications and the amount of PValue was significant (P<0/0001)by ANOVA method.we used also 3 antibiotic as control for Inhibition zone test. Discussion and Conclusion: Silver nanoparticles showed good inhibitory and lethal effects on Gram-positive and Gram-negative bacteria and Also, the nanocomposites produced by the mentioned method have high antibacterial and viscolastic properties.
